TEMPERATURE-REGULATING APPARATUS.

No. 816,046. Specification of Application filed June 6,1

To a witmn it may concern:

Be it known that I, Jenn A. Bennett, of Bayonne, county of Hudson, andState of New Jersey, have invented an Improvement in Tom erature-Regulating Apparatus, of which the following is a specification It isthe object of my invention to auto matically control the flow of atemperature changing mediumsuch as steam, hot water, or arefrigeratingagcntby the movement of a door or windowsash, by which the air, of whichthe temperature has been changed, is allowed to escape from theapartment. The

temperature-changing medium is to prevent waste b shutting oil thetemperature-changing rne iurn when the user of the apparatus prefers toopen doors, windows, or outletsto allow the heated or cooled air toescape in stead of closin off the sup ly of the steam or ternreratureeliangin me( ium. 7 H

ll y invention may e applied as well to the control of a refrigeratingmedium asto iejf; heating medium; but its most interestingsp plicationis to steeni-hcatin systems, and therefore I have illustrated thisapplication of it in the drawings.

In steam-heating systems the amount ng heat transmitted by radiation isin proportion to the difierence in the temperatures of the steam and theexternal air in contact with the radiator, and consequently when a dooror window is opened not only is the heat of the escaping warm air lost,but the admission of cold air to contact with the radiator produces morerapid condensation and conseuent waste of heat, since at such time a remotion and not an increase of heat transmission is desired. under suchcases the waste may be ver great, as the amount of heat transmitted trough a radiating-surface exposed to a strong draft of air at exteriortemperatures may exceed three times the transmission under the normaltemperature 7 that should be retained in the apartment. For theregulation of heating systems the; invention is applicable as well toindirect as to direct systems. i

In carrying out my invention I employ an Letters Patent.

heat transmission the temperature of the apartment under the control ofa suitable valve, and this valve is controlled automatically at will bythe movement of a door, window-sash, or the like whenever the same isopened to allow the heated or refri ereted 'air to escape from theapartment an the exte: rior air to enter. In the preferred constructionthe controlling-valve for the torn eraturc-chsnging medium is operatedby a uidressuremotor, which is In turn controlled the sash or doorcontrolled devices. Many methods are known for controlling motor-valves,and I do not mean to limit my in vention to any one of such knownmethods, as the invention comprehends, broadly, the automatic control atwill by the opening of at door, window, or other outlet of the supply,discharge, or circulation of the temperaturechanging medium.

*"steelfneating in which the air end water of fifzondensation are drawninto the returns by a. pertinl'vscuum or lower pressure maintainedtherein this partial vacuum or lower pressure may be economicallyutilized as the mo- .tive force for operating the motor connected withthe supply-valve. This action of this suction on the motor me becontrolled by the sash or door controlle devices in various ways. it maybe conveniently controlled b a sash or door controlled valve in thebrane suction-pipefroni the return to the motor,

In applying my invention to a system of acting to open communication tothe motor or to open a vent and relieve the suction, and I have shownthis application of my inven- "tion in the drawings, 7

It is also an ob ect of my invention to en-i able the controlling-valveof the tempersture-chan ing medium to be operated from sny' one o aseries of windows or doors and whcii the invention is so applied to avacuuni system of steam-heating to revent by auxiliary valve devices theloss 0 suction or artial vacuum in the return when the vent m the branchsuction-pipe to the motor is open, 7

It is also an object of my invention to eninclosed space, such as aradiator. or'refrigcrating cell, through which the te'mperatpge changingmedium passes-be it steam,

able the 00IliiI'0ll1i1-V&lVB of the temperature-changing me inm to beoperate b liisnd at will to close said valve indepen so iofthe operationof the sash or door con- Wetsr, or a refrigerating fluid-to cliensebvlitre s1 devices.

In the drawings, Figure l is a side elevation of a steam-radiator andone form of my controlling devices arranged to be operated from eitherof two windows. Fig 2 is an enlarged view of part of the same with oneof the motor-controlling valves and the heatcontrollin valve and itsmotor in vertical section. *ig. 3 is a side elevation of a radiator withthe controlling devices arranged to be operated from a single window,the motor-controlling valve and the hcat-control ling valve and itsmotor being in vertical section; and Fig. 4 is a view similar to Fig. 3,showing the air outlet controlled devices combined with an auxiliarytemperatureregulating device controlled by the temperature of theapartment.

a is the radiating apparatus in which the heating medium is to becontrolled. As shown, it is an ordinary steam-radiator having its inletconnected with the supply-pipe b and its outlet with the return-pipe c,in which a lower pressure or partial vacuum is created by suitableexhausting a )paratus. The return-outlet is controlled by a suitableautomatic valve d.

e e are the windows or doors by which the apparatus is to be controlled.

f is the supply-valve, which, as shown, is connected with afluid-pressure motor g, which is operated by the partial vacuum in thereturn 0 under the control of valve de vices controlled by the doors orwindowsash.

h h Ii. 72.3 represent a branch pipe leading from the return 0 to themotor-chamber of the motor g, and interposed in this branch pipe are thesash or door controlled valves. These valves are intended to open orclose the pessage through the suction-pipe to the motor and may be ofany convenient form. As shown, they are constructed as followszi is asuitable casing forming the valve-body interposed in the pipe h h h hWhen the motor is to be controlled by any one of a series ofwindow-sashes or doors, as in Fi 2, there is a controlling-valve foreach, an they are connected up with the sections of the pipe h h h h inseries. In Fig. 1 I have shown a controllingvalve for both the 11 perand lower sashes of each window. P rom the valve-bodyi there is anoutlet to the atmosphere which is controlled by a valve k, normallyclosed on its seat by a spring is. On the valve 7c there is an extensionm, adapted to be struck by a movable piece or lever n, arranged to beoperated by the window-sash or door, so that when the latter is openedthe valve In will be pressed back off its seat, opening the outlet j andbreaking the partial vacuum in the motor. When the windows and doors areclosed, all of theoutlets :1 will be closed, and a partial vacuum willexist in the return 0 and through the pipe h h h k to the motor, and thesupply-valve f will be opened by atmos heric ressure on the m0- tor-diahragm. en, owever, any of the contro ing doors or windows is opened, itwill operate the lover or art n to open the corresponding valve 10 andrelieve the vacuum in the motor and permit the supply-valve to close.

My invention is not limited to any particular form of motor device foroperating the supply-valve but the form shown in Fig. 2 is especialladapted for the purpose. 0 is a motor-diap1ra m which is connected withthe valve-stem y a connecting-frame and is depressed by a spring q toclose the valve f. I prefer to use the connecting-frame p for thepurpose of enabling the valve f to be closed at will inde endently ofthe o eration of the motor. For this purpose I ave shown an eccentric r,having its spindle ournaled in the motor-casing an acting in the frame pto depress it and close the valve f. The eccentric acts in an enlargedopening p of the frame, so that while it is effective for closing thevalve f it cannot be used to open it, as the movement in the op ositedirection will produce no motion in tie frame or valve, which cantherefore be opened only by the motor.

The opening of any one of the valves 7: would, unless means are employedto prevent it, result in a loss of partial vacuum in the return-pipe c,which in an extensive system might be serious. To prevent this, I inter-.pose the valve s in the branch suction-pipe.

This valve acts to restrict the passage-way through the branchsuction-pipe when any of the controlling-valves 7c is opened. Itoperates with the supply-valve f. In the construction shown t is avalve-casing having two sides divided by a web and communicating,respectively, with the section it and section 71/ of the branchsuction-pipe. In th s web is a small port controlled by the valve .9,the latter being normally closed toward its seat by a spring t, butwithout ever entirely closing the port. A projection t on the frame actson the stem of the valve s and fully opens the valve when the frame p 1selevated'i. 6., when the supply-valve f is open. It resultsthat whensteam IS turned on and all of the controlling-valves lc are closed thevalve 8 will be fully open; but when the subply-valve f is closed andthe frame 1) 1s lowered the valve 8 will close down to restrictthe passae through the branch suctlonlpe, and t us prevent the partial vacuum onebeing destroyed. It Wlll be noted that this partlal closure of the valve8 will remain until the valve f7' has again opened and the pro jection tli ts the valve. Therefore after the valves k have closed the exhaustionof air from the motor-chamber will be radual an there will be a slowopening of .t e supply-- alve, while the closing action Wlll be quick,

In Fig. 3 I have shown the apparatus apwith said valve and meansautomatically .plied to a single window or door. In this case therestricting-valve s is not necessary, as the sash or door controlledvalve k may be operated to close the branch k to the return when thebranch h to the motor is opened to the atmosphere. In this constructionthe valve k is of the piston type, projecting throu h the valve-casing1c and carrying a roller 3 on its end, which engages a notch in the sashthe valve beingbprojeoted by a spring la. The branch pipe frornthereturn c opens into a valve-chambegfroni which the pipe It leads to themotor. i5 is a port to the atmglslphere controlled by the'pis ton-valve7c. 1811 the window is closed and the piston-valve is projected, theport In is closed and the pipes in and it are in communication with themotor; but when the .window'is opened the piston-"valve is pushed backand closes the port to the pipe It, wh le opening the port k to the pipeh and permit- --ting the partial vacuum in the motor to be relieved. InFig. 3 I have shown a simple fluid-pressure motor having a diaphragm 0connected with the stem of the supply-valve and depressed by a spring g.

It is desirable in many cases dow-controlled devices should be combinedwith a controlling device controlled by the temperature of theapartment, and such an arrangement is shown in Fig. 4, in which it is avent-pipe from the pipe h to the motor, having its vent 7L controlled bya thermostat it. When the temperature of the apartment does not exceednormal, the vent h is closed; but when the torn erature rises above,

normal the expansion 0 the thermostat it will open the vent and breakthe suction in the motor and close the valve even When thewindowcontrolled valve is not operated. Any suitable form of auxiliarytemperaturecontrolling device controlled by the temperature of theapartment may be used in lieu of that shown and may be operativelyconnected with the motor in any convenient manner.

While I have shown the motor operated by suction, it is apparent that itmay be operated by compressed air or any other motor fluid.
